Usage

Toolbar برای گروه‌بندی controlهای مرتبطی مناسب است که کاربران زیاد به آن‌ها دسترسی دارند. استفاده از toolbar را در این موارد در نظر بگیرید:

  • چند action مرتبط - چند control دارید که functionهای مرتبط انجام می‌دهند، مثل buttonهای text formatting.
  • Keyboard efficiency مهم است - کاربران از keyboard navigation سریع با arrow keyها سود می‌برند.
  • Grouped controls - باید controlها را با separator در sectionهای منطقی سازماندهی کنید.
  • دسترسی پرتکرار - controlها در یک workflow بارها استفاده می‌شوند.

از toolbar پرهیز کنید وقتی:

  • یک button group ساده کافی است - برای فقط 2-3 action نامرتبط، buttonهای جداگانه بهتر کار می‌کنند.
  • controlها مرتبط نیستند - toolbar به یک گروه‌بندی منطقی اشاره می‌کند؛ controlهای نامرتبط کاربران را گیج می‌کنند.
  • navigation پیچیده nested دارید - hierarchyهای عمیق با menuها یا navigation componentها بهتر پشتیبانی می‌شوند.

قابلیت‌ها

Toolbar در Angular یک implementation کامل و accessible برای toolbar فراهم می‌کند با:

  • Keyboard Navigation - با arrow keyها بین widgetها navigate کنید و با Enter یا Space activate کنید.
  • Screen Reader Support - attributeهای ARIA داخلی برای assistive technologyها.
  • Widget Groups - widgetهای مرتبط مثل radio button groupها یا toggle button groupها را سازماندهی کنید.
  • Flexible Orientation - layoutهای افقی یا عمودی با keyboard navigation خودکار.
  • Signal-Based Reactivity - مدیریت state reactive با Angular signals.
  • Bidirectional Text Support - مدیریت خودکار زبان‌های راست‌به‌چپ \(RTL\).
  • Configurable Focus - بین wrapping navigation یا hard stop در edgeها انتخاب کنید.

مثال‌ها

Basic horizontal toolbar

Toolbarهای افقی controlها را از چپ به راست سازماندهی می‌کنند و با pattern رایج در text editorها و design toolها match هستند. arrow keyها بین widgetها navigate می‌کنند و focus را داخل toolbar نگه می‌دارند تا زمانی که کاربران Tab را فشار دهند و به element بعدی صفحه بروند.

Widget groupها

Widget groupها controlهای مرتبطی را در بر می‌گیرند که با هم کار می‌کنند، مثل optionهای text alignment یا choiceهای list formatting. Groupها state داخلی خودشان را نگه می‌دارند و در toolbar navigation هم شرکت می‌کنند.

در مثال‌های بالا، buttonهای alignment داخل ngToolbarWidgetGroup با role="radiogroup" wrap شده‌اند تا یک mutually exclusive selection group ایجاد شود.

input مربوط به multi کنترل می‌کند که چند widget داخل یک group بتوانند هم‌زمان selected شوند یا نه:

html
<!-- Single selection (radio group) -->
<div ngToolbarWidgetGroup role="radiogroup" aria-label="Alignment">
  <button ngToolbarWidget value="left">Left</button>
  <button ngToolbarWidget value="center">Center</button>
  <button ngToolbarWidget value="right">Right</button>
</div>

<!-- Multiple selection (toggle group) -->
<div ngToolbarWidgetGroup [multi]="true" aria-label="Formatting">
  <button ngToolbarWidget value="bold">Bold</button>
  <button ngToolbarWidget value="italic">Italic</button>
  <button ngToolbarWidget value="underline">Underline</button>
</div>

Widgetهای disabled

Toolbarها دو mode مربوط به disabled را پشتیبانی می‌کنند:

  1. Soft-disabled widgetها focusable می‌مانند اما از نظر visual نشان می‌دهند که unavailable هستند.
  2. Hard-disabled widgetها کامل از keyboard navigation حذف می‌شوند.

به صورت پیش‌فرض، softDisabled برابر true است و اجازه می‌دهد widgetهای disabled همچنان focus دریافت کنند. اگر می‌خواهید hard-disabled mode را فعال کنید، [softDisabled]="false" را روی toolbar تنظیم کنید.

پشتیبانی از راست‌به‌چپ \(RTL\)

Toolbarها به صورت خودکار از زبان‌های راست‌به‌چپ پشتیبانی می‌کنند. toolbar را داخل containerای با dir="rtl" wrap کنید تا layout و جهت keyboard navigation معکوس شود. navigation با arrow keyها خودکار تنظیم می‌شود: arrow چپ به widget بعدی می‌رود و arrow راست به قبلی.

Testing

Angular Aria برای testing کامپوننت‌های toolbar، component harness ارائه می‌کند. این نمونه نحوه استفاده از harnessها را در یک component test نشان می‌دهد:

ts
import {ComponentFixture, TestBed} from '@angular/core/testing';
import {HarnessLoader} from '@angular/cdk/testing';
import {TestbedHarnessEnvironment} from '@angular/cdk/testing/testbed';
import {ToolbarHarness} from '@angular/aria/toolbar/testing';
import {MyToolbarComponent} from './my-toolbar'; // Your component

describe('MyToolbarComponent', () => {
  let fixture: ComponentFixture<MyToolbarComponent>;
  let loader: HarnessLoader;

  beforeEach(async () => {
    TestBed.configureTestingModule({
      imports: [MyToolbarComponent],
    });

    fixture = TestBed.createComponent(MyToolbarComponent);
    await fixture.whenStable();
    loader = TestbedHarnessEnvironment.loader(fixture);
  });

  it('should have widgets and allow selection', async () => {
    // Load the toolbar harness
    const toolbar = await loader.getHarness(ToolbarHarness);

    // Get all widgets
    const widgets = await toolbar.getWidgets();
    expect(widgets.length).toBe(3);

    // Click the first widget
    await widgets[0].click();

    // Verify selection state
    expect(await widgets[0].isSelected()).toBe(true);
  });
});
